SEWING-MACHINE BRAIDER.

Specification of Letters Patent.

Application filed August 24, 1914. Serial No. 858,170.

To all whom it may concern:

Be it known that I, ALBERT H. DE Von, a

citizen of the United States, residing at \Vestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Sewing-Machine Braiders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a sewing machine braid-guide through which the braid is led from the rear of the stitch-forming devices to receive stitching passing entirely through the same and into the .body'fabric, thereby exposing the stitching devices unobstructedly to the operator and thus facilitating the handling of the work.

As preferably constructed, the braider comprises a presser-foot having in its pressure member laterally spaced needle-apertures embraced by a braid-delivery guidechannel in the forward part of the under face thereof, a taper leading-in guide-tube of inverted U-shape being extended from the rear through the presser-foot shank and directed between said needle-apertures on the upper face of the pressure member. The forward extremity of the pressure member is preferably transversely notched to afford a braid-turning edge intermediate the upper leading-in guide and the lower guide-chan- 'nel, and adjacent .such notch the pressure member has upon its upper face an arched and wedge-shaped projection for spreading or distending the braid or tape leading from the upper guide to the lower channel in advance of the needle-apertures. By this means, a braid may be led in laterally contracted form between the needles and distended to its full width in advance of the latter so as to pass beneath the same through the guide-channel of the presser-foot to receive lines of stitching along the opposite margins in the laying of the braid upon a body fabric in ornamental patterns. It is evident that the present improvement is applicable to machines employing only a. single needle, the upper leading-in guide being properly formed and disposed to direct the braid wholly to one side of the needle, and that the presser-foot is not a necessary part of the attachment, although desirable,

of a sewing machine provided with the present improvement, Fig. 2 is a sectional side elevation of the attachment upon a larger scale, and Fig. 3 a plan of the same. Figs. 4: and 5 are perspective views of the attachment, taken from different positions, and Fig. 6 is a front end elevation thereof.

As represented in the drawings,the present improvement is embodied in a sewing machine presser-foot comprising the shank 1 of usual form and the foot-plate or pressure member 2 provided in the present instance with the laterally spaced needle-apertures 3 and formed in its under face forwardly of'and embracing said needle-apertures with the downwardly and backwardly inclined braid-delivery guide-channel 4 leading from a transverse notch in the forward extremity of the foot-plate affording a braid turning edge 5 around which the braid is led from the upper face of the pressure member between the forwardly extending toes 6. a v

The presser-foot'shank 1 is apertured adjacent the member 2 to receive the taper leading-in braid-guiding tube 7 of U-shaped cross-section directed between the needleapertures 3 and toward the braid-turning edge 5, the contracted mouth of such tube having a width corresponding substantially with the spacing apart of the needle-apertures, while the flared backwar'dly extending portion terminates rearward of the presser-foot shank in an upwardly inclined lip 8 beneath which the braid is led from the source of supply into the guide-tube.

As represented in the drawings, the central member 7 of the guide-tube, which is U-shaped at the rearward extremity, extends forwardly and merges at the opposite end into a fiat blade or, fin 7". The top of the pressure-plate 2 affords a bottom for the forward portion of the guide-tube 7-which latter is formed in its upper side with the slip 9 for inspection and access to the braid for adjustment by a stiletto or other instrument. p

i The top of the pressure member 2 has in termediate the mouth of the guide-tube and the braid-turning edge 5 a pyramidal braid-spreading projection 10 having a triangular base with one side coincident with the edge 5 and the opposite angle directed intermediate the needle-apertures and toward the guide-tube 7. The said angle of the base of the spreading projection enters the standing fold of the braid or tape as it issues from the guide-tube between the needle-apertures and the wedge-shaped spreader afforded by said projection serves to distend the edges of the tape to facilitate the flattening of the same as it is drawn around the braid-turning edge 5 and advances from the same through the channel 4 beneath the presser-foot.

The resser-foot shank has the usual lateral slot 1 entered by the fastening screw 11 by which said shank is attached to the presser-bar 12 journaled in the head 13 of the sewing machine bracket-arm in which is journaled the reciprocating needle-bar carrying the needle-clamp 1% provided with the laterally spaced needles 15 which cooperate in practice with suitable loop-taking means beneath the bed-plate 16.

As represented in Fig. 1, the braid Z) is folded into flattened tubular form and is led from the source of supply rearward of the sewing machine bracket-arm downwardly beneath the tongue 8 and through the guidtube 7 over the spreader lOrand turning edge 5 and thence backwardly through the lower channel 4 beneath the needle-apertures 3 and across the paths of movement of the needles. The braid'having been inserted as described while the presser-foot was raised, a body fabric m is introduced beneath the presser-foot and the latter is lowered and the stitching proceeded with in the usual manner, the body fabric being turned as required to produce the desired ornamental figure or pattern of the braid thereon,

In applying a braid made from a bias tape, the edge 5 over which the braid is turned may be disposed at a right angle with the direction of feed for laying the braid in a curved pattern, such as that represented in Fig. 1, the longitudinally yielding character of the braid causing it to adjust itself to the face of the body fabric without puckering; but with a braid of which the warp threads run lengthwise thereof, longitudinal elasticity is lacking and there is less adaptability of the braid to such condition. To facilitate the proper laying of such braid in a curved pattern, the turning edge 5 may be made slightly inclined, as represented in the drawings, so that the braid running taut over said edge is thereby crowded slightly to one side against the adjacent guide-toe 6 and toward the center of curvature of the pattern, the outer edge being tightened while the inner edge is slackened in tension, thereby insuring smoothness in the lay of the braid upon the body fabric upon which it is secured by the marginal lines of stitchmg 8.

It is evident that the specific character of the braid-delivery guide through which the braid passes to the stitch-forming and feeding mechanisms is not material to the present invention, as the braid would be effectively positioned for certain classes of work by provision either of a guiding channel 4 in the lower face of the presser-foot or the notch embraced by the forwardly projecting toes 6; but the braid-delivery guide preferably includes both of these elements for confining the braid to a fixed path of movement in its presentation for the stitching operation.

An important and distinguishing feature of the present improvement is the superposed leading-in guide in conjunction with the braid-delivery channel designed to lead the braid from a point rearward of the stitching mechanism and out of the range of action of the latter to a point in advance thereof from which it is directed within the range of action of the stitch-forming mechanism for attachment to the body fabric. It is evident that the improvement is therefore susceptible of very material variation from the present embodiment without departure from the scope of the present invention.

Having thus set forth the nature of the invention, what I claim herein is 1. VA sewing machine attachment compris ing a presser-foot having a needle-aperture and a braid-delivery guide in advance thereof, and a leading-in guide for the braid extending forwardly from the rear of said presser-foot and directed to one side of said needle-aperture and toward said delivery guide, said leading-in guide being of less width adjacent the needle-aperture than the delivery guide.
